- Attached to the pipe adjacent to said opening 11 is the intake fitting 12, the same comprising a casting removebly connected to the pipe and consisting of a central, fun-c :neLshaped depression or passage 18 terininating at its lower end in a downwardly depending cylindric neck 14 forming an opening or passage registering with the opening 11 of the conduit 10. edge of the neck 14: 1S shaped and beveled,

horizontal flange 1'7, preferably rectangular inshape, said flange being preferably sunk 1n the floor with its surface flush therewith. The lntake fitting is removably secured The lower shox'vn in Fig. 3, to conform with the to the conduit by means of a il -shaped bolt or yoke 18 surrounding the conduit and provided at its upper ends with screwthreaded (BXH'QTHHHQSM which proyect up "Ward ly through the Wall of the intake fitting on opposite sidesfof the neclrl l, therebeingz provided for this purpose 0ppositoly disposed depressions or recesses 19,

19 formed in. the wall of the passage 13, said depressions having a horizontal bottom curvature of the inner surface of the con duit and adapted to extend flush with said '15 inner surface of the conduit and close the opening 11 therein when the plug is in clos ing position ,The side wall 21 of theplug is cylindric in shape and-fits snugly in the neck li er the fitting, said wall being proyidcd at the upper marginwith a laterally extending flange forming a downwardly facing annular shoulder at the upper end of said plug and a transversely extending bar 26 adjacent said upper end andjserving :35, as av handle for removing and inserting the plug in the opening.

T 1e plug or closure 22 is supported or I seated in position by the provision of an annular seat or shoulder formed at the no or recess 2 1g surfaces, Within the gro 9/; i

the I [mounted or secured. an annular ring 28,

, preferably rectangular in cross section and iv .of' a thiclmcss to, provide it port on which 4n projects slightly above the-lotion edge of the funnel-shaped passage, or t 4 edge of the oi'iening of the..,ncclrl=i-, the u 1 per surface of the ring forming an minulnr seat upon which rests the'lienge of the so plug or closure i formed oi hard metal of o suitable churnetor, preferably of a degree of hardness greatly exceeding that of the metalof the so conduit or intake fitting, and hence capable of withstanding a much greater degree of Wear or abrasive action. --Although the method of securing the ring in place is immaterial, it is preferred that the ring shell he removable, thus permitting the ring to be easily replaced or renewed from time to time. v

The -enl ventnge oi the construction herein described is manifestly important in the co maiutermnce of systems designed to convey 'd and abrasive material and therefore suoject tounusuzil wear and depreciation,

such as is not experienced in ordinary sy-- terns or pipe lines for conveying liquids or 55 gases or even solid materials of a less abrasive character. The maintenance-of ashesconveying systems and the like would, therefore, entail considerable labor and expense were it not for the provision of means such i as herein described, whereby those surfaces which are exposed to excessive wear can be protected or fortified, not only with a surface of harder metal, but one which can be renewed \vheiiever'necessziry, with very little expense and'lahor. 1 Y

' In connection with an intake fitting such as described, the advantages of a renewable ring or sent are two-foldlirst, that the wean ring eliminates the wear that would otherwise he suffered by the intake fitting, and hence necessitate the frequent renewal of the fitting itself, an exceedingly expensive and laborious operation, inasmuch as a new I fitting is considerably greater in cost than a ring, and. further, the renewal of thefitting would necessitate the tearing up of a; considerable portion of the floor adjacent to the fitting, not to mention the labor and time lost in making the change; and, secondly, the particular location and function of the Wear ring makes it exceedingly desirable toelimina'te weer asmuch as possible, inasmuch as it forms the seat for the closure, which must, so for as possible,be a' true mperend of the neck 14 of the fitting, said scat-being preferably formed, in the follow-' ringfnlennert At the upper end of the aw {sage through said neclnuriddormed or cut in thewsll of'suid neck, is'ztn onnulnr groo e surface in order that a sealing contact can he effectedhetween the plug and its seat, thereby eliminating the leakage of air and the attendant loss of suction in the system when the particular intake opening is not being useflx -'l. he construction embodying the features ofthe inyention are more specifically pointed out in the-appended claims, wherein:
